Specification of Letters Patent.

Application filed February 9,1907. Serial No. 356,532

To (t/Z whom it may concern.-

Be it known that I, J UDsoN M. GRIFFIN, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Check-Protectors and I declare thefollowing to be a full, clear, and eX- aot description of the same, suchas will onable others skilled in the art to which it pertains to makeand use the same,'reference being had to the accompanying drawings,which form a part of this specification.

This inventlon relates to check protectors, and has for its object animproved device of simple construction and easy of manipulation, wherebyany part of an ordinary check in which writing occurs, either in figuresor in full words, may, after the writing has been finished, have itspaper mutilated or partially perforated, without impairing thelegibility of the writing, so that erasure or altera ion of the amountis rendered difficult, if not impossible.

In the drawings :Figure 1, is a perspective of one form of the device.Fig. 2, is an end elevation, partly in section, of the same. Fig. 3, isa plan of a modified form. Fig. 4, is an end elevation of this form.

. ,ifA part of the upper surface of the base 1 has preferably a specialcorrugated surface 2, and at one end of the base, shown in Fig. 1, ishinged a cover plate 3, which extends over its entire length, and whosecenter, which is de signed to he immediately over the corrugated part 2,is cut away to afl'ord access thereto fromabove. At each side of thecover are uides or tracks 4 and 5, under whose over ranging inner edges4 and 5 engage the ends of the journal pin or axle 6 on which isjournaled a mutilating roller 9, which, when the cover is brought downagainst the base piece, engages closely with its corrugations againstthose of the piece 2. Any paper inserted therebetween is roughsued insuch a way that its fiber is grilled or embossed, and any attempt toalter the writing by further penstrokes results in a running of the inkthrough the broken fibers of the paper in a way thatdnstantly destroysall negotiability of the check in the eyes of an experienced person.

If merely that portion of one line on which the amount of the check iswritten in figuresis to be grilled, a short stroke of the handle 19 andthe roller 9 is sufficient, but if, in addition, the entire line inwhich the amount is written out at full length, or the line contain- InFigs. 3 and 4, is illustrated a type of this device in which the hingingof the rollersupporting portion to the base portion is along a side,instead of one end.

The slide rod 1 1 is supported between the inclined supports 12 and thebracket 13 is slidably ournaled thereon, and its possible range ofmovement limited accordingly. The modification in the form of the casing14 here used from the type shown in Figs. 1 and 2, is seen to becomparatively slight. In this type the holding effect on the check ofthe cover plate 2, (which as such is omitted), is taken by leaf springs15 at each end of the base, under which the check is slipped to theposition desired before the roller is applied.

What I claim is: 1. In,oombination with a base having a 1grilled uppersurface, means hinged thereto or holding a paper in place thereupon,said means being wholly free from interfering enga ement over thegrilled portion, and a gri led roller adapted to be moved lengthwise ofthe grilled surface, bein guided within and confined to a path compementary in extent therewith, substantially as described.

2. In a check protector, in combination with a grilled base, amutilating' roller adapted to coact therewith in mutilating a sheet ofpaper inserted therebetween, means hinged to the base for holding thepaper in place, and a guide member whereby the possible range ofmovement of the roller is limited, substantially as described.

Y 3.. A check protector, having in combination with a mutilating roller,9. base portion adapted to support the check and to co-o'perate with theroller in the mutilation of selected portions of its surface, means hinedto that part of the base portion whose sur ace is not pressed upon bysaid roller for holding the check in place during the movement of.
